Method for realizing mechanical production of crop hybridization seeds by using fluorescent protein gene markers

Abstract

The invention relates to a method for realizing mechanical production of crop hybridization seeds by using fluorescent protein gene markers. Fluorescent protein gene used as a marking trait is introduced into a hybridized combination parent through a transgenosis and hybridization mode, plants the seeds of which have enough identification expression of the fluorescent protein are selected to reproduce so as to breed a parent with the fluorescent protein gene. When the first generation seeds of the hybridization seeds are produced, the parent seeds are mixed according to a needed proportion and sowed. After the hybridization seeds are ripe, a mechanical mixing method is adopted for harvest, and the first-filial generation seeds are separated and collected by using a color-selection machine with fluorescent identification. By adopting the production method of the hybridization seeds, the whole-course mechanization of the hybridization seed production can be truly realized, the production cost of the hybridization seeds can be greatly reduced, the production efficiency of the hybridization seeds is greatly improved, the purity of the hybridization seeds can be ensured, and the hybridization seeds with great amount, high purity and low cost are provided for crop producers.

Description

technical field [0001] The invention relates to a method for realizing mechanized production of crop hybrid seeds by using fluorescent protein gene as a seed identification mark. Background technique [0002] The use of heterosis in crops in the world today is an important way to increase crop yield. The production of hybrid seeds is an important link in the use of heterosis. Reducing the production cost of hybrid seeds and improving the purity of hybrid seeds are very important elements for realizing the use of heterosis. Hybrid seeds have been widely popularized in my country for rice and corn. However, due to the impossibility of mechanized production in planting and production, the production cost is high, and farmers pay more for using hybrid seeds. Although hybrid seeds have been successfully produced for crops such as wheat and soybeans, the high production costs lead to Scientific and technological achievements cannot be popularized and applied on a large scale.
